Embodiment 1

[0023] Such as figure 1 As shown, a desk with both heat preservation and earthquake escape functions includes a table top 1, table legs 2 fixed on the left and right sides of the table top 1, and pedals 3 arranged between the table legs 2, and the lower part of the table legs 2 is opened There is a cavity, and an adjusting device is arranged in the cavity, and one end of the adjusting device is connected with the pedal 3 , a roller 4 is arranged on the lower surface of the pedal 3 , and a heating plate 5 is respectively arranged on the desktop 1 and the table legs 2 .

[0024] In this embodiment, when an earthquake comes, the students can immediately hide in the desks to avoid being injured by falling debris, and at the same time, the students can use the hand-operated adjustment device to move the pedal 3 down until the roller 4 is in contact with the ground. When the desk is used as a protective device, students can push the table under the table to move outwards to escape f...

Embodiment 2

[0026] Such as figure 2 As shown, this embodiment is based on Embodiment 1, and the adjustment device includes a bearing 6 fixed on the upper end of the inner cavity of the table leg 2, a fixed rod 7 arranged in the bearing 6 for rotation, and a gear connected to the end of the fixed rod 7 A8 and the gear B9 meshed with the gear A8; also include the screw mandrel 10 connected to the central axis of the gear A8, the nut 11 matched with the screw mandrel 10, the pedal 3 is connected with the nut 11; on the side wall of the table leg 2 There is a groove 12, and the two ends of the nut 11 are slidingly arranged in the groove 12 of the table legs 2 on both sides; it also includes a handle 13 whose one end is connected with the central axis of the gear B9, and the other end is located outside the cavity of the table leg 2.

[0027] In this scheme, the operation process of the adjustment device is as follows: the student turns the handle 13 by hand, the rotation of the handle 13 wil...

Embodiment 3

[0029] Such as image 3 As shown, on the basis of Embodiment 1 or Embodiment 2, this embodiment also includes a power supply unit electrically connected to the heating plate 5, and the power supply unit includes a solar panel 14, a storage battery 15 and a switch 16 connected in sequence by wires , the switch 16 is connected to the two poles of the heating plate 5 through wires. The solar panel 14 can convert solar energy into electrical energy during the day and continuously supply power to the desks, thereby realizing the utilization of energy.

Abstract

The invention relates to a desk with heat insulation and earthquake escape functions; the desk comprises a desktop, legs fixed on the left and right sides of the desktop, and a pedal arranged between the legs; the lower portion of the legs is provided with a cavity; an adjusting device is arranged in the cavity; one end of the adjusting device is connected with the pedal; the bottom surface of the pedal is provided with rollers; the desktop and the legs are respectively provided with a heating board. The adjusting device and the rollers are arranged, so the student can hide in the desk so as to push the desk to move outside the classroom as soon as possible; the heating board on the desktop and the legs can heat up the desk so as to warm the students, thus improving learning efficiency of the students in winter.

Description

technical field [0001] The invention relates to a desk, in particular to a desk with the functions of heat preservation and earthquake escape. Background technique [0002] Students need to use desks to read and write at school, but winter is relatively cold, and the temperature is too low to easily affect the work efficiency of students. Furthermore, geological disasters are frequent now, often without warning, and once they occur, there is no way to escape. The school is densely populated and the students' escape skills are relatively poor. During the earthquake escape process, they are likely to be hit by collapsed and fallen tiles, causing personal casualties. Contents of the invention [0003] In order to solve the defects that the desk does not keep warm and students are easily injured during the earthquake escape, the invention provides a desk with the functions of heat preservation and earthquake escape. [0004] Technical scheme of the present invention is as fo...
